Grundfos Alpha ECM Pump
Description The new ALPHA takes reliability in small domestic circulators to new heights. Even in systems where the operational environment is a challenge, the ALPHA will ensure long-lasting trouble-free operation with no risk of blockage. If you want to leave your customers with a completely trouble-free heating solution, the new ALPHA is a premium choice.
ALPHA is versatile and efficient whether you use one of its seven speed, pressure control settings, or simply leave it on the factory setting AUTOADAPT™.
The ECM motor design reduces energy consumption by 50%, and in AUTOADAPT mode, will automatically analyze the heating system, find the optimum setting, continue to adjust its operation to changes in demand, and reduce power consumption by up to 85%. This to ensure the lowest possible energy consumption without sacrificing comfort.
The Grundfos ALPHA circulator with AUTOADAPT are predicated on:
65-years of hydronic experience of how pumps work in countless applications and operating environments
15+ years of ECM motor experience in the market
ALPHA materials and design resist blockage from magnetite and iron oxide particles found in closed hydronic systems.
